To find the value of k, we can compare the y-coordinates of the original point and the translated point. The original y-coordinate is -1 and the translated y-coordinate is 2.
We can subtract the original y-coordinate from the translated y-coordinate:
2 - (-1) = 2 + 1 = 3
So, k = 3.
A point is translated on the coordinate plane from (4,-1) to (4,2). Journey writes the function g(y)=y+k to describe the translation. What is the value of k?
